I am in the planning stages of my bathroom remodeling project. I have a standard 60" bathtub which I would like to replace with a whirlpool tub. I am looking at the Jacuzzi Model Cetra which is 60" long with a tile flange and the integral skirt for access to the motor. Do you have any experience with this tub or can you recommend another brand or model with similar specs. Also, does a tub like this require any special installation like a mud base used on bigger whirlpools? What about extra joist supports?Thanks for the help.
